The paper presents investigation under chatter stability in micromilling process. To determine the impact of micromilling machine dynamic properties, impulse test of micromilling tool was carried out. Due to high participation of ploughing in micromilling process the regenerative effect in comparison to conventional milling can be reduced or lead to frictional vibration. Series of cutting tests for variable cutting speed, feed per tooth and cutting depth were performed to verify these assumptions. During the tests cutting forces and accelerations, both on machine spindle and workpiece were measured. Performed milling tests show that the vibration occurs at highest depth of cut and at lowest feed rate. This leads to the conclusion that reason of vibration could be friction between tool and workpiece.
